(2) Section II, "Table of Drugs and Chemicals ." This section is not used by
the Army. Instead, Appendix C of the Individual Patient Data System (IPDS) User's
Manual is used. This User's Manual is a publication of the U.S. Army Medical
Department Center and School, Directorate of Patient Administration Systems and
(3) Section III, "Alphabetical Index to External Causes of Injuries and
Poisonings." These terms are not medical diagnoses, but describe the circumstances
under which an accident or act of violence occurred (i.e., the underlying cause or means
of injury). Use of this section by the Army is limited. It will be discussed later in this
b. As mentioned earlier, Volume 2 is arranged alphabetically (see figure 2-3). In
first order are the main terms (names or nomenclatures of diagnoses). Next, are the
modifiers of the main terms. Main terms are printed in bold face type. Modifiers are
indented under the main terms. As you see in the example below, each level of
indentation modifies or relates to the level above it. The arrangement is similar to that
of an outline.
(1) Modifiers indented 2 spaces modify or relate to the main term.
(2) Modifiers indented 4 spaces modify or relate to the nearest 2 space
(3) Modifiers indented 6 spaces modify or relate to the nearest 4 space
(4) The same principle applies regardless of the number of levels of
indentation under a main term.
